about vray passes

[3dchamp]

hi anyone
plz tell me that the what function of diffuse, specular, reclection, refraction,
shadow in vray render elements.

They are the same as those in MentalRay. If you are beginner, do not bother about those as those are used by the professional/advanced users to compost the render and have more control about it (the brightness, darkness of shadow etc.). As all of us know, diffuse will be the 'colour', specular will be almost the same as reflection and refraction is refraction. (you should have known all these things before you try to use any material, unless you are just using pre-made materials.)

Thanks.
